ruby-on-rails - 错误：安装oj时出错：

我刚刚第一次从GitHub克隆了一个存储库。

我去了我的本地机器上查看它，所以在我的Mac上的本地存储库中我运行了以下命令

bin / rails服务器

我收到以下错误：

无法在任何来源中找到activesupport-5.0.0.1 运行gem install oj -v '2.12.14'以安装缺少的宝石。

然后我按照建议运行了bundle install命令，但后来它给了我以下错误

安装oj（2.12.14）时发生错误，Bundler无法继续。在捆绑之前确保ERROR: Error installing oj: ERROR: Failed to build gem native extension. current directory: /usr/local/lib/ruby/gems/2.4.0/gems/oj-2.12.14/ext/oj /usr/local/opt/ruby/bin/ruby -r ./siteconf20170218-3717-1p2bvl9.rb extconf.rb >>>>> Creating Makefile for ruby version 2.4.0 on x86_64-darwin16 <<<<< creating Makefile current directory: /usr/local/lib/ruby/gems/2.4.0/gems/oj-2.12.14/ext/oj make "DESTDIR=" clean current directory: /usr/local/lib/ruby/gems/2.4.0/gems/oj-2.12.14/ext/oj make "DESTDIR=" compiling cache8.c compiling circarray.c compiling compat.c compiling dump.c dump.c:503:8: warning: implicit conversion loses integer precision: 'long' to 'int' [-Wshorten-64-to-32] cnt = RSTRING_LEN(rstr); ~ ^~~~~~~~~~~~~~~~~ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/ruby.h:976:6: note: expanded from macro 'RSTRING_LEN' RSTRING_EMBED_LEN(str) : \ ^~~~~~~~~~~~~~~~~~~~~~ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/ruby.h:972:6: note: expanded from macro 'RSTRING_EMBED_LEN' (long)((RBASIC(str)->flags >> RSTRING_EMBED_LEN_SHIFT) & \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ dump.c:503:8: warning: implicit conversion loses integer precision: 'long' to 'int' [-Wshorten-64-to-32] cnt = RSTRING_LEN(rstr); ~ ^~~~~~~~~~~~~~~~~ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/ruby.h:977:28: note: expanded from macro 'RSTRING_LEN' RSTRING(str)->as.heap.len) ~~~~~~~~~~~~~~~~~~~~~~^~~ dump.c:1776:39: warning: 'rb_struct_ptr' is deprecated [-Wdeprecated-declarations] for (i = (int)RSTRUCT_LEN(obj), vp = RSTRUCT_PTR(obj); 0 < i; i--, vp++) { ^ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/ruby.h:1190:33: note: expanded from macro 'RSTRUCT_PTR' #define RSTRUCT_PTR(st) rb_struct_ptr(st) ^ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/intern.h:889:25: note: 'rb_struct_ptr' has been explicitly marked deprecated here DEPRECATED(const VALUE *rb_struct_ptr(VALUE s)); ^ dump.c:1776:37: warning: assigning to 'VALUE *' (aka 'unsigned long *') from 'const VALUE *' (aka 'const unsigned long *') discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers] for (i = (int)RSTRUCT_LEN(obj), vp = RSTRUCT_PTR(obj); 0 < i; i--, vp++) { ^ ~~~~~~~~~~~~~~~~ 4 warnings generated. compiling err.c compiling fast.c fast.c:816:17: warning: 'rb_data_object_alloc' is deprecated: by rb_data_object_wrap [-Wdeprecated-declarations] doc->self = rb_data_object_alloc(clas, doc, 0, free_doc_cb); ^ /usr/local/Cellar/ruby/2.4.0/include/ruby-2.4.0/ruby/ruby.h:1379:1: note: 'rb_data_object_alloc' has been explicitly marked deprecated here rb_data_object_alloc(VALUE klass, void *data, RUBY_DATA_FUNC dmark, RUBY_DATA_FUNC dfree) ^ fast.c:1280:24: error: use of undeclared identifier 'rb_cFixnum' case T_FIXNUM: type = rb_cFixnum; break; ^ 1 warning and 1 error generated. make: *** [fast.o] Error 1 make failed, exit code 2 Gem files will remain installed in /usr/local/lib/ruby/gems/2.4.0/gems/oj-2.12.14 for inspection.

按照建议，我跑了：gem install oj -v＆＃39; 2.12.14＆＃39;

然后我收到了一条非常长的消息，警告和错误（见下文）。有什么想法吗？
